There is a lot of confusion between medical grade air purifiers and other kinds of purifiers. What exactly does it mean? And, how is it different from other types of air purification devices? These are just some of the questions you may be interested in.
First, let’s define medical grade. HEPA (high efficiency particulate air) filters are medical grade because they meet the specifications set forth by the American HEPA regulatory agency. Yes, and also by the United States government. Medical grade air purifiers with lower grade HEPA filters can catch virtually all sized particles, including those smaller than the size of the virus. However, these filters are specifically designed to specifically remove particulates larger than the size of an eraser on a pencil.
There are some air purifiers out there that claim to use medical grade air purifiers, but which ones do you really need? The answer is not entirely clear, since it depends a lot on where you live. Some places have strict laws about what particles smaller than 10 microns can be filtered out. If this is the case in your area, you need to look for only those purifiers that use a HEPA filter to keep these particles from getting through.
On the flip side, some places have very lax laws about what HEPA particles are allowed to go through. So, if you find medical grade air purifiers that advertise their ability to trap larger particles without using a filter, you may want to think about looking elsewhere. You should also be aware that there are several different kinds of purification systems, including portable models and permanent types. You will want to do some research to decide which type is best for you.
In some cases, if you get an air purifier that uses a charcoal filter, it can remove large particles such as smoke, dirt, mold, dust mites, pollen, cigarette smoke, roasting fumes, etc. However, the drawback to these purifiers is that they remove oxygen from the air. Ozone and UV light are able to lighten many colors, including black, white, and even gray, so these particles are not as harmful as other, less effective particles. They are, however, able to kill bacteria, viruses, germs, and sometimes even allergens. The best kind of air purifier for removing air borne pathogens is a carbon-based filter that filters out larger particles while leaving in the smaller, essential oxygen molecules. This method is the most effective at removing odor and allergen particles.
One important thing to keep in mind when choosing an air purifier is that in general the more expensive the model, the more effective it is at keeping particles out of the air. However, there are some exceptions to this rule. It may be that the cheap model you are looking at doesn’t have an activated carbon plate, or it might not have a HEPA filter. This means it will effectively remove many particles that other brands will miss. If it does not have a carbon plate, it probably will not have a good purifying power, because the particles it removes all come through as airborne particles. So, if you want to make sure you are getting your money’s worth, consider getting the most expensive model you can find.
